SASH HOLDER AND FASTENER.

SPECIFICATION forming part of Letters Patent No. 649,212, dated May 8, 1e'oo. Application filed July 21,1899. Serial No. 724,597- (No model) reference marked thereon,.which form a part of this specification.

This invention relates to sash-locks of the class designed to be secured to the windowcasing and operating to bind the sash; and the objects in View are to provide an improved gravity-wedge lock adapted to limited spaces for application, as for upper sashes, and also adapted for the lower sash, and particularly to provide such a look as shall bind the sash in two directions to more surely prevent the rattling thereof in the frame by windcurrents. Other objects are to provide a positive lock and one protected againstordinary tampering therewith and-which may be cheaply manufactured and be durable and economical in use.

The invention consists in providing a wedgechannel so formed that a gravity-wedge descending therein and in contact with a window-sash shall cause the sash to bind both against the slide-strip at the opposite or outer side of the sash and against the side of the window-frame opposite to that at which the lock is attached, an improved gravity-wedge provided with a transverse slit or recess at its lower portion, adead-lock bolt of novel Referring to the drawings, in which like letters and numerals of reference in all the figures indicate like parts,Figure 1 represents a fragmentary perspective view of a window, illustrating the application of my invention; Fig. 2, a front elevationof my look as adapted more particularly for use with a lower sash and showing both the gravity-wedge and dead-lock partly projecting as when in operative position; Fig. 3, an elevation of the operative side of that shown in Fig. 1; Figs. 4 and 5, plan views of the interior of the case; Figs. 6 and 7, detail views of the gravity- Wedge; Figs. 8 and 9, side elevations of the two parts of the case; Figs. 10, 11, and 12, front, rear, and side views, respectively, of the dead-lock controller; Fig. .13, a perspective view of the dead-lock; Fig. 14, a trans Verse sectional view taken on a line X X in Fig. 2'; Fig. 15, a fragmentary detail view showing the front of the lock as particularly adapted for use with the upper sash; Fig. 16,

- In practically carrying out my invention I cases the cap may be retained by wood-screws whichsecure the wholecase to the window frame or easing.

While I show two forms of look as being sometimes desirable under certain conditions,

in many cases the lower-sash lock D. maybe used with an upper sash B, and the uppersash lock E may be used with a lower sash A.

When the slides a or b are set in grooves in the window-frame O, I provide a thin lip d,

. may be used.

and leaving but a thin part in the groove, and in this case the lip (1 extends over the slide and bears upon the more solid frame at the edge of the groove, so that the lock is prevented from tilting over when the weight of the sash is upon the wedge. I also preferably provide angular screw-holes e, so that the retaining-screwf may enter the solid wood of the frame 0 and tend to draw the look toward the sash.

The pattern of lock D as I preferably construct it consists of the body F and cap G, constituting the case, and gravity-wedge II, the dead-lock I, the controller K, and the key R. The case has an oblique angular channel in which the wedge works, and is formed by side walls h and h, which are disposed angularly to the basej of the case, and a bottom bearing U and U, the latter being permissibly formed entirely in the body portion. To prevent undue friction, the wedgebearings preferably have recesses 7;,so that the bearing contactis not continuous. The eifect of the laterally-angular channel is to cause the wedge after biting the sash to force the sash to the opposite side of the window-frame at the same time that it is being clamped against the slide-strip at the side of the sash opposite the lock. The cap G'has an angular slit S and in some cases a continuing slit S, extending to the edge of the cap, in which the shank of the finger-hold P or Q of the wedge works. The wedge 11 has a slit or recess m, extending from its lower end upward nearly to its upper end, to receive the deadlock bolt 1, so that the whole lock is not required to be excessively long; but when the dead-lock is not employed a solid wedge O The bolt I works in a recess in the body F and between guides 15 and u. The controller K is in the form of a cam and has a stem 3, working in a circular bearingsocketein the base of the body F, and a beveled circular frictional flange IV, bearing against a corresponding lip V at the edge of an aperture 2 in the cap G, these frictional bearings being designed to prevent accidental rotation of the controller, as well as intentional movement,without the use of the proper key R therefor. At the outside of the flange W is preferably a projection J, having a central recess in which is a key-post L in alinement with the stem 3, and a key R, havinga suitable socket, is adapted to be applied to the key-post when operating the dead-lock. This socket may be open at the top, as at 6, or it may be closed. The periphery of the projection J acts as a journal in the aperture 2 and preferably extends slightly at the front of the cap G, and the back 5 bears against the thin bottom part 11 of the dead-lock bolt I, this bottom being preferably two connecting strips across the opening in the bolt, at the frontof which is a bearing 7, engaged by the cam to push the bolt out, and at the back a bearing 8 to withdraw the bolt. The bolt is rectangular in plan, having guide edges 12 and 13 bearing at t and 11, respectively, and is of sufficient thickness to neatly fill the slit m in the wedge.

While the lock D may be used withan upper sash, usually the dead-lock is not required, and in the interest of economy I usually construct the upper-sash look more simply, as E, the body M of the case having the angular wedgechannel above described and a solid wedge O, and the cap N has a lip 14 at the side of the case extendingto the lip d, and usually has a depression 15, in which the finger-hold Q works.

The sides Z and n of the wedge and bolt, respectively, being preferably milled, I provide a sash-protector T to prevent abrasion of the face of the sash, and it is composed of a thin strip of suitable material, as a composition of lead and alloy, having holes r and secured to the sash by nails or screws. In Fig. 1 a portion of the slide a is broken away to partially expose the protector, which is of suitable length to correspond with the travel of the sash relatively to the look.

In operation the gravity-wedge constantly presses against the sash except when raised manually. Thus the sash is prevented from dropping when not counterbalanced by weights, and the upper sash cannot be lowered except by releasing the wedge pressure against it. To prevent the lower sash from being raised, the dead-lock bolt is forced against it and withdrawn to release it.
